Cladder

A proof of concept utility that takes two arguments, a source directory and a destination directory.

The src directory is turned into a lz4hc-squashfs archive and then mounted onto a destination directory with tmpfs overlayed ontop of it to make it writeable.

A possible use is to download a source code repo and then build it, and throw away the tempoary build files.

Requirements

System/Runtime

• Linux Kernel supporting squashfs and overlayfs, and iptables-dev installed

Toolchain

• GCC or Clang
• libc
